The invention provides a three-material injection molding glass assembly. The three-material injection molding glass assembly comprises glass and a covering edge. The covering edge covers at least one surface of at least one edge part of the glass. The covered edge comprises a first covered edge layer, a second covered edge layer and a third covered edge layer. The first edge covering layer is arranged on at least one surface of the edge part of the glass in an injection molding manner, at least part of the second edge covering layer is arranged outside the first edge covering layer in an injection molding and covering manner, and the hardness of the second edge covering layer is greater than that of the first edge covering layer. At least part of the second edge covering layer is coated with the third edge covering layer in an injection molding mode, and the hardness of the third edge covering layer is smaller than that of the second edge covering layer. Different from the prior art, according to the technical scheme, the glass is wrapped by the first edge wrapping layer, the second edge wrapping layer is wrapped outside the first edge wrapping layer in an injection molding mode, the glass and the first edge wrapping layer are tightly attached, the first edge wrapping layer and the second edge wrapping layer are tightly attached, and the situation that the sealing performance and the waterproof performance of the glass assembly are affected due to shrinkage and edge warping of the hard second edge wrapping layer is avoided.

    本申请提供了一种三料注塑的玻璃总成,包括玻璃和包边。包边包覆玻璃至少一个边部的至少一个表面。包边包括第一包边层、第二包边层和第三包边层。所述第一包边层注塑于玻璃边部的至少一个表面上,至少部分所述第二包边层注塑包覆于所述第一包边层外,所述第二包边层的硬度大于所述第一包边层。所述第三包边层注塑包覆于至少部分所述第二包边层,所述第三包边层的硬度小于所述第二包边层。区别于现有技术,上述技术方案用第一包边层包覆玻璃,第二包边层注塑包覆于第一包边层之外,使得玻璃和第一包边层、第一包边层和第二包边层之间紧密贴合,避免硬质的第二包边层收缩翘边影响玻璃总成密封性和防水性。
